Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid 'engineered living materials' are made by embedding cells in an inanimate matrix that's formed in a desired shape. Now, researchers have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.

Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.

Scientists report significant progress in cultivating nephron progenitor cells (NPCs), the cells destined to form the kidney's filtration system, the nephrons. NPCs hold immense promise for understanding kidney development, modeling diseases, and discovering new treatments. The team improved the chemical cocktail for generating and growing NPCs in the laboratory, enabling the sustained growth of both mouse and human NPCs in a simple 2-dimensional format.

Conditions such as diabetes, heart attack and vascular diseases commonly diagnosed in people with spinal cord injuries can be traced to abnormal post-injury neuronal activity that causes abdominal fat tissue compounds to leak and pool in the liver and other organs, a new animal study has found.

Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new study is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing system that allows them to make rapid decisions independent of their genes.

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells -- the cells that have a specialized function, like skin and muscle cells -- they remain elusive in the first cells of our bodies, the embryonic cells. Embryonic mitosis is notoriously difficult to study in vertebrates, as live functional analyses and -imaging of experimental embryos are technically limited, which makes it hard to track cells during embryogenesis.

Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.

Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.

In a scientific breakthrough, researchers have revealed the biological mechanisms by which a family of proteins known as histone deacetylases (HDACs) activate immune system cells linked to inflammatory bowel disease (IBD) and other inflammatory diseases.

An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.

Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.

Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.

Trying to hit a target size before dividing seems like the best strategy for maintaining a precise cell size, but bacteria don't do that. Now we know why.
